A customer reports a problem of no dial tone (NDT). Upon inspection, the technician notices that new carpeting has been installed. What should the technician do next? - CORRECT ANSWER: Look for a cable that runs under the carpet; it is likely that the cable has a short from the carpeting tack strip.
A transmitter outputs 100 milliwatts (mW). An antenna cable connects the transmitter to an amplifier, and the power into the amplifier's input measures 50 mW. The amplifier increases the signal to the original transmitter's power level and sends the signal to the antenna. The antenna receives the signal from the amplifier at 75 mW, and then transmits at 150 mW. What is the intentional radiator's (IR) power level in this radio
frequency (RF) circuit? - CORRECT ANSWER: 75 mW
Access points (AP) must support what encryption techniques in order to comply with
IEEE 802.11i security standards? - CORRECT ANSWER: Temporal Key Integrity
Protocol (TKIP), Advanced Encryption Standard (AES), and AES-CCMP (Counter- Mode/CBC-MAC Protocol).

After a digital TV (DTV) service problem has been analyzed and possible causes considered, what is accomplished by isolating the various network elements? -
CORRECT ANSWER: It narrows the scope of likely problem sources.
After resolving the problem with the premises wiring issue, which of the following is the next step in the six-step process that the technician should take? - CORRECT ANSWER: Verify that the problem has been resolved and that phone service is running perfectly on all phones.
All 802.11 standards use one of two frequency bands. What are these frequency
bands? - CORRECT ANSWER: 2.4 GHz and 5 GHz bands.
Although there are many different implementations of spread spectrum technology, what are the only types specified by the FCC in the Codes of Federal Regulation (CFR),
volume 47, part 15? - CORRECT ANSWER: Direct Sequencing Spread Spectrum
(DSSS) and Frequency Hopping Spread Spectrum (FHSS).
An independent basic service set (IBSS) is also commonly referred to as which one of
the following? - CORRECT ANSWER: Ad hoc network.
As a general rule, how does an increase in effective isotropic radiated power (EIRP) relate to the link budget range? - CORRECT ANSWER: Each 6 decibels (dB) increase in EIRP equates to a doubling of range.
As a subscriber enters a hotspot area, what signals their mobile wireless device of an
available Wi-Fi network? - CORRECT ANSWER: The access point (AP) advertises to
the wireless device to enable connection.
Because the spectral density of a quadrature amplitude modulation (QAM) channel is much higher than that of an analog TV channel, what is done to ensure equal power in all channels in a network with analog and digital modulation channels? - CORRECT
ANSWER: Operate the analog TV channels at higher amplitude level than the QAM
channels.
